Abstract:

The question of whether and how bilingualism affects domain general cognition has been extensively debated. Less attention has been paid to the cognitive abilities of speakers of different variants of the same language, in linguistic situations such as bidialectalism and diglossia. Similarly to the bilingual situation, in bidialectalism and diglossia speakers need to use only one variant of the language in a given context. However, these situations provide fewer opportunities for mixing or switching between the variants, potentially leading to different domain general cognitive outcomes than those reported in bilingualism. Here we review the available evidence on the effects of bidialectalism and diglossia on cognition, and evaluate it in relation to theories of the effects of bilingualism on cognition. We conclude that investigations of bilingualism, bidialectalism and diglossia must take into account the conversational context and, in particular, the opportunities for language switching that this affords

New pre-print: The effects of bilingualism on the structure of the hippocampus and on memory performance in ageing bilinguals

Abstract:

Long-term management of more than one language has been suggested to lead to changes in cognition and the brain. This is particularly documented in older age, where bilingualism is associated with protective effects against decline, for example, affording compensation for symptoms of Alzheimer’s disease leading to delayed diagnosis relative to non-bilinguals. Herein, we focus on potential bilingualism effects in the hippocampus, a brain structure related to memory that is particularly vulnerable to cognitive ageing. Hippocampal volume has been shown to increase as a result of second language learning and use in younger adults. However, we do not know if this is maintained over the lifespan, that is, what the long-term effects might be examined in ageing. Herein, we examine hippocampal volume and performance in episodic memory tasks in healthy ageing long-term bilinguals compared to monolinguals. Results show greater hippocampal volume for the bilinguals, which was correlated to individual-level quantified use of the two languages. Thus, our results mirror that of immersive active bilingualism in younger populations. No significant effects of bilingualism were reported on episodic memory task performance. Our findings suggest that long-term active bilingualism leads to neuroprotective effects in the hippocampus, which we discuss in the context of the proposed bilingualism-induced brain reserve in older age literature.

The conference programme is now available to download here

 

The conference will take place in the form of a Zoom webinar and is now FREE OF CHARGE. However, we ask you to please register using this link.

Please note that only registered attendees will receive the link to access the webinar.

Our colleagues at the University of Massachusetts have done a great job of hosting CUNY online in March, and we have decided to follow a similar format for COM2020. To get an idea on how the conference will be set up, you can take a look here.

ABOUT COM2020

The Conference on Multilingualism has its origin in 2005 at the University of Trento, where it was known under the name of “Workshop on Bilingualism”. In 2016, the conference was renamed to “Conference on Multilingualism” in order to include a broader range of aspects of multilingualism. It is aimed at exploring the many different aspects of multilingualism in the fields of linguistics, psychology, neurology, sociology and educational sciences. In the past, it was held in Ghent and in Leiden. In 2020, it is coming to Reading!

LANGUAGES ON THE MIND – THE EFFECTS OF BILINGUALISM ON MIND AND BRAIN

Language is frequently in the headlines, from worries about people speaking too many languages or too few, to questions of whether bilingualism protects against cognitive decline in later life. Bilingualism has featured prominently in language debates, with stories often over-simplifying a more complex picture.

Cut to the heart of recent research on brain and language. Follow researcher Toms Voits on a journey through the uniqueness and complexity of the human brain’s capacity for language. This public lecture will introduce the ways in which two or more languages co-habit within a single mind, the processing issues of co-operation and competition between languages which arise from that, and the much-debated effects of bilingualism on mind and brain. With a focus on research on bilingualism in older adults, the lecture will examine some of the complexities that need to be unpicked in order to understand relationships between ageing, cognitive health and language.

New pre-print: Bilingualism and brain development

Abstract

Bilingualism affects the structure of the brain in adults. This is indicated by experience-dependent gray and white matter changes in brain structures implicated in language learning, processing, or control. However, limited evidence exists on how bilingualism may influence brain development. We examined the developmental trajectories of both grey and white matter structures in a cross-sectional study of a large sample (N=711 for grey matter, N=637 for white matter) of bilingual and monolingual participants, aged 3-21 years. Metrics of grey matter (thickness, volume, surface area) and white matter (fractional anisotropy, mean diffusivity) were examined across 41 cortical and subcortical brain structures and 20 tracts, respectively. We used generalised additive modelling to analyse whether, how, and where the developmental trajectories of bilinguals and monolinguals might differ. Bilingual and monolingual participants manifested distinct developmental trajectories in both gray and white matter structures. As compared to monolinguals, bilinguals showed: a) more gray matter (less developmental loss) starting during late childhood and adolescence, mainly in frontal and parietal regions (particularly in inferior frontal gyrus pars opercularis, superior frontal cortex, inferior and superior parietal cortex, and the precuneus); and b) higher white matter integrity (greater developmental increase) starting during mid-late adolescence, specifically in striatal-inferior frontal fibers. The data suggest that there may be a developmental basis to the well-documented structural differences in the brain between bilingual and monolingual adults.

Abstract:

Brain plasticity associated with second language acquisition and learning has been a focus of research in the past two decades. Recent research on cognitive neuroscience has enriched current understanding on the neurological underpinning of second language learning. Beyond behavioral findings, examining brain functions and structures provides a biological explanation of how language acquisition (as a natural experience) and learning (as an active skill and knowledge acquisition process) shapes the human brain. Together, combining cognitive neuroscience methods and second language acquisition and learning has offered an opportunity for cross-disciplinary collaboration. To facilitate cross-disciplinary understanding and potential research collaboration, this review paper aims to provide an overview of the major cognitive neuroscience methodologies adopted to study second language acquisition and learning. A selection of empirical studies covers second language acquisition in developing children, bilingualism as a naturally-occurring experience, and short-term second language learning in laboratory settings. Brain structural (diffusion tensor imaging, DTI; and voxel-based morphometry, VBM) and functional (electroencephalography, EEG; and event-related potentials, EPRs) methods are briefly discussed with suggested further readings. The paper ends with future directions using these methodologies to explore brain changes in response to second language teaching and learning experience.
